No way to request seats. Seats are (I believe) still assigned by your reservation. The seats are assigned by when you make your reservations. The best seats should go to the guests according to when they made their ADRs. If you make your ADRs early, you should get a pretty good seat. There are stairs to climb so if someone in your party is in a wheelchair or cannot walk steps, you can request floor seating. HDDR is great. We went last year and are headed back again this year too.
